Just buy S2. Its about 40 USD. Thats affordable. You already got a DFP. You can see what varieties of types of racing/driving LFS has to offer online, as in bangers, rally, cruising, drifting, stunting, and demo durby, as well as the racing itself. LFS is a very good simulator, and S3 wont come out for a while, so there is enough time to enjoy S2. When there is a new patch that comes out it does not affect your S2 license. It will affect it when S3 comes out, meaning you will have to buy the S3 "update"
